1'7 Claims.

This is a divisional application of the fol1owing mentioned: Edwin Hopkins, application No. 402,714, filed October 26, 1929, Teleticket system, issue date of patent June 11, 1935 (allowed Sept. 20, 1934, issue extended three months): patent number to be 2,004,112.

The main purpose of my invention is to provide means for printing theatre tickets by telegraph at a number of stations located at various distances from the theatre. Thus stations in drug stores and elsewhere throughout a city may print tickets for any theatre in the system, the printing being under the control of the theatre to which tickets are desired.

In a system of eighty theatres fitted with sending apparatus and a thousand stores in which are located printing apparatus, any such station may telephone any theatre and when it is ascertained that the theatre has tickets acceptable to the purchaser visiting the station, the theatre sets the printing apparatus by telegraphic signals over the telephone wires and the station operator then operates the printer, the theatre operator automatically cancelling his ticket at the same time. The theatre operators sending apparatus permits him to send signals which will only print tickets for his theatre. But he may have a printer and thus be able to secure tickets for any other theatre if desired by his patron.

It is also within my invention to keep a group of sending machines and supplies of tickets to all theatres at a central office, and outlying stations may obtain their tickets through the central station. In such case the sending apparatus is fitted with means for selling tickets for all theatres. One sender may be fitted for a small group of theatres and if a distant patrons does not wish seats available for any of these, the call may be switched to another small group without compelling the patron to telephone to a number of different theatres from the printing station.

The apparatus consists chiefly of a sending apparatus adapted to be set by its keys to send a series of electrical impulses in groups of alternating impulses, prolongations of one such impulse and dead spaces, from a series of sending discs coming into action automatically in succession, and a receiving-printing apparatus with a multiple number of type wheels adapted to be set to the printing position by the several groups of impulses, automatically in succession. When the type wheels are thus set the printer station operator prints the tickets by manual operation. The printer then clears itself automatically, but the sending operator by changing a single key may send the adjoining seat without resetting his apparatus, when he clears by manual operation when through, automatically cancelling the tickets sent.

Further features of the invention will be found set forth in detail hereinafter:

In carrying out my invention I find it generally desirable to employ the herein described apparatus and manufactures, but it is to be un- 10. derstood in carrying out the objects of my invention, less than all of the different means, mechanisms, and manufactures herein described may be employed for some uses, or parts only may be employed, or other mechanisms and manufactures similar may be employed and substituted, and while the preferred forms of my invention are shown, it is to be understood that many of the structural details and-steps resorted to may be varied and many changes in details and steps resorted to without departing from the scope and spirit of my invention, nor do I limit myself to the specific devices, manufactures and methods shown, although I believe them especially suited to the ends to be attained by the invention.

The accompanying drawings are largely diagrammatical and are not to be considered as working drawings of the invention, but merely as illustrations of the principles of the invention. Many parts of the apparatus are omitted from particular figures and in particular figures different planes are taken and portions forward of the planes are indicatedand the juncture of planes is not always indicated, for the purpose of clearness of illustration of the invention without the multiplication of drawings.

The sending apparatus illustrated in Figs. 1 to 13 comprises twelve sending discs with commutators on their peripheries adapted to send alternating current to line. These commutator discs I are mounted to rotate freely on shaft 2. Attached to one side of the disc is retracting spring 3, and to the other side gear 4 through a friction drum 5, illustrated in detail in Figs. 9 and 10.

Fig. 1 is a sectional elevation on line AA of Fig. 13. Fig. 11 is a sectional plan of the left end of the apparatus. Contact-breaking magnet 20 is shown on a plane approximately indicated by line B of Fig. 1. The clutch magnet 9 is shown on the plane indicated approximately by line C of Fig. 14 and the clutch arm and crowbeak-sector system on the plane indicated apend elevation on line P proximately by line D. The front portion is about on line E of Fig. 1.

Gear 4 is driven by spur gear 6, mounted to rotate freely on shaft 1. Slideably feathered to shaft I are clutches 8. These clutches drive spur gears 6 when thrown into engagement by clutch magnet 9, through bell crank lever Ii].

Clutch magnets 9 are supported by an arm to rear wall 4| of framework I2. A table stud of the arm II supporting the clutch magnets carries contact springs I3, arranged so that the contact is made when the magnet is energized and broken when it is de-energized. Attached to bar I8 of bell crank armature lever I0 is a spring which tends to keep the clutch open, but which is overcome when the magnet is energized.

A description of the sequence of operations of these magnets, circuits, springs and mechanical parts will be given later in connection with diagram 25.

A crowbeak ratchet composed of arm 54 and beak I5 is mounted on a stud in framework I3, adapted to rotate in a vertical plane. A small spring at its axis tends to force arm I4 downward. Beak I5 is hinged to bar I4, so that its point is free to move towards the aXis of bar I4, but a small spring acts in opposition to movement in that direction, the small spring being at its axis. The beak cannot move away from the axis of bar I4, by reason of shoulders at the axis of beak I5.

A table arm I6 extends from the framework towards the clutch, and carries sector I4, which is mounted on a stud in I6 to rotate partially in one direction or the other in the horizontal plane. The inner arm of lever arm i6 is bevelled to a median line, which pushes the apex of sector I'I back and forth as the clutch operates. As seen in Fig. 11 the clutch is open. Sector IT is held in the normal median position by a small axis spring. When bar I8 moves to close the clutch 8, the apex of the sector is carried along with it until bar I8 passes it, when the sector flies back to normal. When l8 opens the clutch it carries the apex along in the other direction until it passes it and the sector flies back to its normal position.

The point of beak I5 rests on sector I! at times in the cycle of operations and at other times on table I6.

Figs. 7 and 8 show the three positions assumed during operation. When the apparatus is cleared to begin functioning the clutch is open, the sector is in the median position and the crowbeak rests on the sector as shown in Fig. 8.

As shown in Fig. '7 right hand example, the clutch is closed. This drives the fan side of the sector to the left, sliding under beak I5, but not letting beak I5 fall to the table I5. These two examples show the clutch open at the outset and the clutch closed to operate the spur gear 6, the gear 4 and the disc I. When disc I is stopped by a key, clutch magnet 9 is automatically deenergized and the spring of arm I8 throws the clutch out of engagement. This causes the fan side of the sector to move to the right, which permits beak I5 to fall to table I6. As this takes place arm I4 closes switch I9, which completes a local circuit to energize the clutch magnet of the next disc unit. Beak I5 is so hinged to bar I4 that it may be forced back in the position seen in the left example of Fig. 7.

In Fig. 7 the left hand example of beak and clutch have operated and the clutch has been disengaged. All the units will assume this position when the whole apparatus has functioned.

The right. hand example of Fig. 7 is in operation. and the example in Fig. 8. is awaiting operation. It is in the position assumed after being cleared by manual operation from the position in the left hand example of Fig. '7.

Contact breaking magnet 2Il is attached to the framework by a lug, and standards 2| carry armature 22 on lever 26, making contact with pillar 23 for the line alternating circuit. The breaking of this contact breaks the line. Ratchet arm 24 is pivoted to lugs in the framework, and has tooth, 25, which engages the end of armature lever 26. Thus when the magnet is energized bar 26 is drawn in and caught by the tooth and contact at pillar 23 is permanently broken even after magnet 20' is de-energized. Foot 21 of arm 24 rests on universal lifter bar 28, extending across the whole apparatus, and it supports all the feet 21', which are depressed by springs 29. Spindle 30, rotating in the sides of the framework and in standards 2| carries cams 3I affixed to it. Manually operable crank 32 is affixed to spindle 3t and when it is rotated it lifts all the feet 2'! and arms 24 and allows springs 33 to draw back the armature lever and re-make the contacts at pillars 23. This manual operation of crank 32 takes place after the mechanism has functioned in order. to clear the levers for the next operation.

Universal bar lifter 28 has attached to it arms 34, which extend down and under crowbeak bar I I and lift the crowbeak levers at the same time ratchet 24 is cleared. This brings beaks I5 up to rest on sector IT, as shown in Fig. 8. This breaks I contact I9 on the local clutch magnet circuit.

Contact I3 is broken by the de-energization of the clutch magnets, which breaks the line circuit.

Shaft I on which the slideable members of the clutches are mounted is driven by a motor 35', with a pulley 35, belt 31 and pulley 38 on shaft 1.

Shafts 2 and 'I are fixed in standards 39 which extend from the floor 40 to rear wall II.

Disc I bears a commutator peripherally, with side annular rings 43, 44, connected to alternating segments as 46, as seen in Figs. 4, 5 and 6. Insulation 4'! is placed between the segments of the commutator. Brush 42 rests on the periphery and the segments pass under it, while brushes 59, contact with annular rings ift. MI, thus supplying current of opposite phase, and brush IB thus passing alternating current to line of a frequency depending on the width of. the segments and speed of disc I.

The keyboard with keys as 5|, in twelve rows, is provided. The rows are as follows:

The rows of. keys number from left to right. The illustration shows thirty six keys in a row. This only applies to rows of seat numbers. Other rows have a fewer number or a greater number of keys as required, although where a greater numher is. required it. is better to have alternative rows as in the case of H and HH. In Fig. 8 rows and H. are shown, while the short row in which the. keys are marked R, L, C, l, 2, 3, 4, 5, 5; and I indicate locations, right, left, center and sections 1 to. '1.

In rows. A and AA a key will be noticed at the top marked SK. This stands for skip, and causes: the disc to stop at the first segment of the commutator and transfer the functioning to the next disc. The reason for this is that no ticket con-I'd be for more than one row, and when the iicket is printed the space of. the row skipped is left blank- The number of seats in the row is: also provided with a skip key. Where the number of theatres is greater than can be containedon one printing wheel, a second will be supplied with skip keys for keys for the two rows of theatre keys.

The keys, as M, are mounted on'plungers as 52', with notch 53, peg stop 54 and spring 55, as detailed in Figs. 2 and 3. The section of the key at the end is a fliat rectangle.

The keys: are journalled in three walls, the front or face wall 56, the working wall 51, parallel to the face wall and the rear wall, 58, a cylindrical wall curved about the periphery of the discs for about 145 degrees. One key of each row except the skip rows, in which case the skip key is: used, is pushed in. They are automatically caught and held in.

Disc: I- carries stud 59.. When disc I rotates counter clockwise, as seen in Fig. 1, stud 59 will presently encounter the keyheel which has been pushed in. Meanwhile in rotating a number of alternating impulses are sent to line. If the top key is presented only one impulse goes to line, if the bottom key, thirty six impulses or eighteen alternations. When the disc is stopped a prolongation of the final impulse goes to line, which functions to cut. out the disc and set the next disc in operation.

The prolonged impulse throws the clutch out of engagement, when spiral spring 3, which has been slightly wound up during the rotation of the disc throws the disc back to its initial position, stud cc of disc I striking standard Iii, which supports wall 58.

Motor 35 is. started by manually closing switch and switch 63-throws in the main line. When the motor is running and the line is thrown in spur gear 6 drives gear 4, but disc I is prevented from rotating by mechanical stop 64 engaging lug 65 on disc I. Switch 63 closes the line indirectly through closing a local battery circuit which energizes clutch magnet El throwing clutch into engagement and closing main line. Stop 64 has springs 36 and flange 61. The spring draws it inward. When pulled out manually it releases disc I. Stop 64 and lug 65 are bevelled so that when spring 3 drives disc I back, stop 36 again engages lug 65 automatically.

Supplementary stops for all the discs are shown at the bottom of Fig. 1. Stop arm 64a. is pressed against stop BI] by spring 65a. It is pivoted in lugs on the floor and is fixed to spindle IiBa, which is turned by a crank manually depressing fi la below stop 60 and allowing discs to turn.

Friction drum 5 is illustrated in detail in Figs. 9 and 10. Cup 68 is fixed to disc I. Disc I rotates freely on shaft 2. Gear 4, which has a boss hub I59, rotates freely on shaft 2. Afiixed to boss E59 is disc Ill, which rubs the inner face of cup 68. Disc III has four wings as II, cut through and bent down. The lower ends rest on the face of disc I; the portions marked I2 in Fig. 10. The wings are of springy material and force faces is and l6 together. While gear 4 rotates and disc I is free to rotate, the pressure of. wings H is sufficient to carry disc I along, but if disc 3 is stopped, wings ll continue to rotate along with boss 69 and gear 4, and rub over the face of c I, starting it instantly it is released. As there is only a small load on disc I, wings II need press only lightly on disc I.

In order to hold the keys in the operative position when they are depressed and to release them singly or in totality simultaneously, means are provided as shown in detail in Figs. 2 and 3. The lower part of Fig. 2 is an elevation of the face wall 56 and two keys with a wing thumb piece.

The upper part of the figure is a section with the face wall removed. Key plungers 13, "I4 are idle position. Key plunger I5 has been depresser to the operative position. Latch levers IS, 1?, I8 are provided, pivoted on stud screws I9, 89, 8|. Mounted on stud screws also are leaf springs 82, s3 and 84 which force the latch levers a ainst the sides of the key plungers. When the hey plunger is depressed, its notch 53 is engaged by the latch lever, and its end, as 85, is held in the path of stud 59 of disc I, and brings disc I to a stop when stud 59 reaches end 85. In order to return a single key, as 86, to idle position, wing thumb piece as 8'! is provided. Through axis stud it is affixed to a latch lever and may be manually operated in opposition to latch lever spring to lift latch lever out of notch in plunger and allow spring to return plunger to the idle position.

Sliding in guides as 8! on the inside of the face wall 56, are a set of combs as 38, terminating at the bottom each in a bar as 89, sliding in slots in walls 56, 57, the outer end of which, SI], serves as a key for the manual depression of the whole comb, in opposition to spring 9I which normally holds the combs in the upper position. The comb 88 has teeth as 92, 93, 94 which engage the ends of levers as I9, 80, 8|. When lever 18 falls into notch 53, tooth 94 stops lever end BI and the depression of key will clear the key similarly as would the operation of thumb piece 81.

In order to clear all the keys at once, a universal depressing bar extends across the apparatus and bears on the inner ends of bars 89. Universal bar 95 is hinged by arm 96 to a pivot in lugs 99. Three of these are sufiicient, one at either end and one in the middle. Cam shaft its extends across the apparatus and has cams IQI and handle crank I02. When I02 is rotated manually cams IIJI strike arms 98 and depress so the universal bar, carrying down all the combs and freeing all the keys. Distance piece m3 extends from base El of wall 58 to wall '51 at the bottom. The walls are attached at the top to top plate I94 of the framework.

It is desirable to cancel at the theatre the ticket, duplicate of which is being printed at the outlying station. For this purpose slot I05 in the side wall I SE? of framework I2 is provided. The ticket is thrust in endwise, guides I 01 controlling its direction. It comes in contact with end I08 of lever Hi9 pivoted in lugs Ill End I08 is held down by spring I I2. When end of ticket lifts I98 up electrical contacts at the other end, II3-I M are made, being in series with switch 63 which would not close its circuit unless I I3I I4 was also closed. It is thus necessary to introduce a ticket to start the apparatus.

In order to deface the ticket, punch I I5 on the end of lever IIS, pivoted in lugs III, is opposite a hole in the base plate III, and it is driven down through the ticket. Cam II8 on shaft I00 drives lever IIS down when shaft I60 is rotated manually to clear the keyboard. Shaft IIIO is journalled in side I06 of framework, and in lug IIH near side I20 of framework I2.

The diagram, Fig. 23, shows the electrical connections. In the diagram the first unit at the right has been operated, the second unit is in operation and the two units to the left are awaiting operation. Only four units are indicated but as many more as may be desired may be inserted, preferably between units two and three. The diagram, generally speaking, is viewing the apparatus from the rear, looking towards inside of keyboard. The operations begin on the right of the figure and work towards the left.

To operate the apparatus the following steps are taken. A ticket is inserted in slot I05, thus closing contacts II3IM.' The motor 35 is turned on by switch 62. Shaft I now begins to rotate idly. All the clutches 8 are open. The operator closes switch. 63, This completes local circuit AaI. It comprises local battery or other source of direct current, I22, magnet A9 and contact I23 at armature of magnet Aa20. The initial position is best seen at B2920, as Aa20 as shown has already functioned. The completion of circuit AaI energizes clutch magnet A9 and this attracts armature AIG. The initial position is best seen. at CIS and the completed position at BIB. The drawing down of armature AIII completes main line circuit A2, but it cannot yet send impulses to line as disc AI has not started to rotate. The depression of A I 0 causes clutch A8 to engage, as best seen at B8. Spur gear A6 rotates and drives gear A4, but as disc AI is held by stop 6465 it cannot rotate. Take-off brush 48 rests on insulation at the initial point.

Line circuit A2 starts at line batteries AI 25 and AI 26 with their opposite poles to earth, connected by brushes 49, 56 to commutator annular rings of disc I, thus supplying current of opposite sign as the disc rotates. Lead A goes to contact I24 where it is completed by armature AM. It then goes to magnet A029 and from thence to line.

At this point the apparatus is in readiness for operation, the line being earthed at the outlying station. The functioning begins when stop 64 is manually released. Disc AI begins to rotate and sends alternating impulses to line which operate the outlying printers initial typewheel. When disc I is stopped by stud 59 striking a key heel set for that purpose, a prolongation of the last impulse is sent to line.

Magnet AaZII is so wound that the alternating impulses do not affect it, but when the impulse is prolonged the magnet functions, and draws down its armature Aa2II. This armature is caught by ratchet AaM, and remains in that position until cleared manually at the close of the operation, by crank 32. The depression of armature Aa22 breaks contact I 23 and opens circuit AaI permanently. This de-energizes magnet A9 which permits clutch A2 to be disengaged and breaks contact I2 3. Thus the line goes dead by automatic action on the functioning of the prolonged impulse. Clutch A8 being disengaged, spring 3 returns disc Al to its initial Contact I24 completes the line circuit. i

position. Thecommutator of the periphery cannot send any impulses to line onithe retraction of disc I as the line is broken at I24. There is accordingly a dead space .on the line momentarily.

When armature AM is released it allows. arm 18 of bell crank L0 to pass to the left as seen in Fig. 11. This causes the fan part of sector '11 to be pushed to the right, and allows crowbeak it to fall to table it, and thus close contact 1 9. The sector is not illustrated in the diagram, but crowbeak l5 and arm M are indicated in the lowered position making contact AM].

The closing of A19 completes local circuit Bbrl, which passes through direct current battery 12], contact EH28 and clutch magnet B9. It energizes B9 and causes contact .5129 to be made, setting up the main line circuit B2, which :derives current from batteries B1 25, B4 20. This circuit passes on through brush B48, lead B to contact I29, magnet Bb20 and thence to line. The line remains dead as .disc BI does not rotate until clutch B8 engages, which is momentarily after the making of contact 129. Upon. disc Bl rotating, alternating impulses pass to line until the disc is stopped by a key :heel, when :a prolonged In the illustration of thefigure 23 the unit B is in .operationand unit A has zceased to function. When the discs are stopped by the key heels the friction drum5 between disc "I and gear 1 permits shaft 7 and spur gear 0 tocontinue to rotate gear 4 while disc I is held at rest.

When disc Bi is stopped by a key heel, a :prolonged impulse goes to line, which energizes magnet Bb20, and attracts armature B1222, breaking contact BN8, while B1222 is locked up by ratchet B1924. This breaks circuit Bbl which de-energizes magnet B9, and frees B00, which then takes the position shown in 'the diagram by Alli), breaks contact 129, which makes the line dead, and-disengages clutch B0. The fall of crowbeak B15 makes the contact B1 9 and sets up the local circuit Col.

Local circuit 'Ccl includes contact BI Q, local direct current battery C130, magnet 09 and contact CHM. It energizes C0 and :completes :line Brush .048 draws alternating impulses from batteries C125, C520 which proceed through 'lead C, contact 132 and 'magnet C020, and thence to line. The subsequent closing of clutch C8 starts disc C l which sends the alternating impulses. When a:key heel stops disc Cl, the prolonged impulse energizes magnet C020, breaks contactCl'B l, armature CdZZ being locked up by-catch C024. Whenlocal circuit C0! is broken by Cl3l, magnet C9 tie-energizes, line circuit C2 is broken at I32 and local circuit Dell is made by the fall of crowbeak Cl5 making contact Cit. Clutch C8 is disengaged.

Local circuit Ddl includes contact CIQ, direct current battery E33, magnet lDQ and contact D.|34. This energizes magnet D9 and sets up main line circuit D2 by making contact I35. Circuit D2 starts at batteries Dl25, Dl20, thence through brushes of ,disc DI to lead D, contact I35, magnet The closing of clutch D3 starts disc Di and sends alternating impulses to line. The prolongation of the last impulse energizes magnet Dd20. Contact Dl'-34 is broken, and armature D0122 is locked up by catch D24. This :de-energizes magnet 'D9, .breaks contact I and makes line D2 dead. This completes the cycle of functions, as crow beak D|5 has no function to perform in de-energizing afurther local circuit.

The operator now prepares theapparatus for a new cycle by opening switches 62 and 63. Crank 32 is turned which clears the ratchets of the line magnets and prepares contacts for the local circuits, returning the parts to the positions indicated .at C9, CLO and Bb20.

The operator then rotates crank 102 which clears the keys and defaces the ticket at I05, which is then withdrawn.

In case a ticket such as EH24 has been printed and the next ticket is to be the adjoining one .at EH25, the operator does not clear the keys with crank 102, but clears key 24 with thumb piece 81, and sets key 26. He leaves ticket EH24 in slot and causes the machine to operate as before. At the conclusion he defaces ticket EH24,

removes it and inserts ticket EH26 and .deiaces it by a turn of the crank 102, which only moves cams 8:8 idly as they have already released the keys.

The line I30 is superimposed on telephone line L38 by .=apparat,us 030, well known in the art. Telephone J31 enables the operator to converse with the printer operator to ascertain .what tickets are wanted, and to have the printer setting read back to him before printing to avoid mistakes.

The apparatus thus functions to send selected groups of signals to :line, each group comprising a selected number of alternating impulses and a prolonged impulse at the .end and .a dead space,

These impulses and spaces are used .to operate the ,printerat the outlying station.

The printer is illustrated in Figs. 14 to 22 inelusive.

The printing machine consists of a series of typewheels with type on their peripheries corresponding to the keys of thesending machine, and means for setting such typewheels successively, and for printing the ticket by manual operation.

The typewheels are caused to rotate by gears, driven by "a motor through intermediate gears as later described. Typewheel "201 contains the names of the various theatres arranged parallel to the axis. To it is affixed gear 202 of considerably smaller diameter. Next comes a partition, supported by the base, but bearing afixed type, H, which indicates the number of the outlying station. As once a printer is installed it remains at .its station, so this number does not need to be succeeded by anyother. It appears on all tickets. Other stations, of course, have difference numbers von this partition. .Another partition, 204, is marked with the initials E. P., T. P., To.,, and .A. 0. These stand for the words Established price, Tax paid, Total price and Admitone. This reading matter is the same for all tickets, and this portion is, accordingly, permanently fixed.

Typewheel 205 is marked 4 A0 and 4.40. These figures stand for $4.40, $0.40 and $4.40, comingopposite the words Established .price, Tax ,paid and Total priceiof the partition .204, respectively. Where the price is $3.O.O-,or less and no tax .is paid, the figures opposite Tax ,paid are omitte'd. Attached to .typewheel 205 is gear .206.

' designation, which rows run from A to Z.

Typewheel 2H bears the names of the months of the year. Attached to it is gear 212.

Partition 213 is permanently supported by the base. The letters HH on it stand for the name of the apparatus and appear on every ticket. The remaining portion of the ticket from this point on is the coupon to be torn off at the theatre door and retained by the patron. It bears duplicates of price and dates, and has additional data.

The typewheels bearing duplicate matter are driven by the same shaft that drives the original, and thus do not require additional sets of keys on the sender.

Typewheel 2|4 again bears the year date, 1929. To it is attached gear 2l5.

Typewheel 216 bears the day of the month again, and attached to it is gear 2ll.

Typewheel 2I8 bears the month again, and attached to it is gear 2| 9.

Typewheel 220 contains the days of the week, not used before, and also distinguishes between matinees and evenings. Attached to it is gear 22I.

Typewheel 222 bears the figures I0. This is a number corresponding to the name of the theatre as on typewheel 20!. Thus the identification of the theatre is made on the coupon after it is detached, data which need to be familiar only to the employees of the theatre. Gear 223 is attached to typewheel 222.

Typewheel 224 bears the prices, as $4.40, indicating the total price. It is operated in conjunction with typewheel 205. Gear 225 is attached to typewheel 224.

Typewheel 226 bears the number l0l, indicating a seat number. On this wheel are numbers from 10! to I35, usually center section numbers in a theatre. Attached to typewheel 226 is gear 221.

Typewheel 228 bears figures 2|. This is also one of a set of seat numbers, ranging from 1 to 35, usually side section numbers. In printing a ticket either typewheel 226 or 228 is used but not both, the unused one being skipped by the skip key. Gear 229 is attached to typewheel 228.

Typewheel 230 carries letters, I-IH. This is a row designation, which rows run from AA to ZZ. Gear 23l is attached to typewheel 230.

Typewheel 232 shows letter I-I. This is a row In use either 230 or 232 is used but not both. The one not used is skipped. For these skipped wheels, the periphery at the initial point bears no type, and leaves a blank space on the ticket.

Gear 233 is attached to typewheel 232.

Typewheel 234 shows word Right. This is a location by sections or aisles. Gear 235 is attached to typewheel 234.

Typewheel 236 bears the designation Orch, being a floor designation, as orchestra, balcony, etc. Attached is gear 231.

The gear and typewheel units are mounted to rotate freely on fixed shaft 238, set in standards 239, 240 in the base.

Mounted to rotate freely on shaft 24l, fixed in standards 242243 are seventeen gears as 244, to engage gears 202, 206, 208, 2l0, 212, 2l5, 2H, 2|9, MI, 223, 225, 221, 229, 231, 233, 235 and 231. These gears all engage gears 244 which in turn are engaged by gears of equal number mounted to rotate freely on fixed shaft 245, mounted in standards 246, 241, which standards also serve to journal rotating shaft 248, with grooved pulley wheel 249 and pulley cord 250.

Script wheels, partitions and gears 251 to 281 inclusive correspond to typewheels, partitions and gears 201 to 23'! inclusive. The script wheels and partitions are similar in size to the type wheels and partitions, and bear in readable script the same symbols as are borne by the typewheels and their partitions reversed to print from. The symbols on the script wheels and their partitions are visible through a window in the top of the cover, indicated by dotted lines 288 in Fig. 14, being above the plane of the paper of this sectional plan.

The gears afiixed to the script wheels, the intermediate gears 244, and the gears affixed to the type wheels are all of the same size. Thus through window 288 may be read the data which will be on the ticket when printed. If any mistake is made by the operator of the sending machine, it becomes obvious to the operator of the printer before printing, and the printer may be cleared and the error corrected before printing.

Beneath the script wheels are seventeen pairs of gears, as 289, somewhat larger than the script wheel gears, but not necessarily so. They are attached to the shaft by friction drums 46| as seen in Figs. 21 and 22 in details.

Shaft 248 is driven by pulley 249, cord 250 and pulley 290 on shaft of motor 29L Motor 29| runs continuously during operation. It is turned on by switch handle 292 closing switch contacts at 293 when the machine is to be operated, and is turned off manually afterwards.

Gears 289 would rotate script and typewheels continuously if not prevented, but when a typewheel and script wheel are stopped, shaft 248 continues to rotate, and will drive any of the Wheels immediately they are released, through the friction drums 46l.

In order to stop the typewheels at the proper locations so that the selected ticket may be reproduced, a set of twelve escapement units are provided, six on one side and six on the other.

A detailed side elevation of the escapement unit is shown in Fig. 15. There are twelve units, one for each row of sender keys. Some of them control two typewheels that are duplicates, as the date and price on ticket and coupon. Twelve shafts are controlled by the escapement units, six at one end and six at the other, in six lines, two units being at the outer ends of a pair of shafts in line.

Escapement shafts 294, 295, 296, 291, 298, and 299 at the front or lower end of Fig. 14 are respectively in line with shafts 300, 30l, 302, 303, 304 and 305 at the rear end.

The escapement shafts 294 to 305 inclusive have gears afiixed to them, driven by the gears of the typewheels and of the same size. When the escapement shafts are stopped the typewheels and script wheels are also stopped.

Shaft 294 has gears 294G, which controls typewheel 226, bearing seat numbers, as IN. This is effected through gear 221 which engages gear 294G.

Shaft 300 is in line with shaft 294, and has gear 360G, controlling typewheel 236, indicating floors, as Orch. This control is effected through gear 231 on typewheel 236. Shaft 300 is journelled in standard 300W and 300W2, which are attached to the side wall but are broken off in the drawings, as they attach above the plane of the paper. Shaft 294 is similarly journalled but standard 294W is omitted from the drawings.

Escapement shaft 295 carries gears 295G and 295G2. Gear 295G controls typewheel 2H (March) through gear 212 on the main part of 75 the ticket and gear 295G2 controls typewheel 2l8 (March) through gear ZIS, on the coupon part of the ticket.

Shaft (iiil is in line with shaft Shaft 3i)! carries gear MiG which controls typewheel 23!) (HI-I) through gear 23!. Shaft 3c! is journalled in standards iiillW' and SMWZ, which go to the side wall. Shaft F295 is similarly journalled.

Shaft 2% has gears 295G and 296(32. Gear 296G controls typewheel 2% ($4.40) through gear 2% on the main or admission portion of the ticket, while 296G? controls typewheel 224-, ($4.40) through gear 225 on the coupon part of the ticket.

Shaft 362 is in line with shaft 2%. It has gear 362G which controls typewheel 2234 (Right) through gear Shaft ii iifi is journalled in standards 3MB and M92132, the latter not shown, which extend to the floor. Shaft 2% is similarly journalled.

All the remaining escapement shafts are journalled in. standards which extend to the base or floor of the machine, and which are bent and off set to reach the fioor without interfering with other members. These standards are mostly broken away in the drawings for the sake of clearness.

' Shaft 529i controls two typewheels bearing the day of the month, and. shaft 363 in line with it controls seat number typewheel 22 i (Seat'number 21.)

Shaft 42% controls two typewheels bearing the year, (1929) and shaft 306 in line with it controls typewheel 226, (Thursday evening.)

Shaft 229 controls typewheel 2M (theatre) and typewheel (it, number of theatre), and shaft 3%, in line with it, controls typewheel 232 (row letter H.)

These seventeen forms of changeable data are thus controlled by twelve escapement units and shafts.

The escapement units are similar although placed at different angular attitudes as regards shaft 238.

As seen in Fig. 15, framework of unit 38"! is attached to standard M28 which may be affixed to wall or base.

Frame SE38 carries magnet 39S, positioned perpendicularly and magnet ii! 9, positioned horizontally. Escapement arm Si! is pivoted in frame 3H2, and has cross bar stop end M3.

A. pair of escapement wheels are provided, affixed to escapement shaft as 29%. They are provided with teeth. The teeth of one wheel are staggered with respect to the other by the amplitude of half the pitch of a tooth. When the arm 3!! moves back and forth from one to the other, the teeth being driven towards the bar stop end sit, the shaft rotates by an angle equal to half the pitch of a tooth at each movement, or a whole tooth on a stroke back and forth. Magnet till is a polarized magnet and so arranged that when the arm 3 is drawn to one side it remains there until drawn to the other side by alternations of current received from line.

Thus. the alternating impulses from the sender allow the escapement shafts to advance the printing wheels to the selected printing point.

On the prolonged impulse the arm 3M remains where it was drawn. When the time for clearing the escapement wheels comes, local current is applied to magnet 3M, it being direct current. Magnet 3109 being energized, stop M3 is lifted with arm til from whatever tooth it happens to other.

be in, and the escapement shaft rotates, in a counterclockwise direction as seen in Fig. 15. Arm 3H is pivoted in frame 302 which in turn. is pivoted in standards 3i63i"i on spindle Bit, while end CH9 of arm 3H carries armature 328. Magnet 3&9 attracts this and thus lifts arm til i. Magnet 3539 overcomes spring 32f which ordinarily holds arm 3H on the escapement Wheels.

In order to stop all the escapement wheels at the initial point, irrespective of how many teeth have escaped, a contact breaker composed of spring leaves 322-323 is provided. The circuit of magnet 3% is in series through this breaker.

Cam 324 is fixed to shaft 295. As it rotates after the shaft is freed by the lifting of lever arm 3i i, it presses down contact leaf spring A space free of teeth is provided on the escapement wheels, beginning at point 325 and extending to high tooth 326. On the type and script wheels a similar blank space is provided, no letters appearing on that space.

Leaf spring 323 and spring (-3222 and cam 32 are so adjusted that contact at point 32] is broken just after point 325 on wheel Lil i has passed stop M3. M9 thereupon, allows spring 32f to retract arm 3i! and stop tit strikes the toothless portion between 325 and 326. When high tooth 32B strikes stop 3 iii the shaft stops. Similarly all the shafts are thus stopped at the initial point of the high tooth. The high tooth is provided in case arm 3!! does not descend quickly enough. The wheel 354- must then stop at the initial tooth whether the magnet has released arm til in time or not. Cam 324 serves an additional pur pose in that it dampens the momentum of the shaft towards the end of the rotation, so that the shaft is rotating much more slowly when point 325 is reached than it was earlier. Cam 552 i slips off the end of leaf spring 323 at the moment arm 3!! and stop 3!? strike high tooth 3%. Thus it is in working position even on the first impulse of the alternating current. The breaking of contacts 321 breaks other contacts automati y so that the remaking of 321 does not time cause 359 to be energized again. The alternating impulses from the sending having caused the first escapement unit to function are automatically switched on to the next unit so that the series of typewheels are positioned one after the The symbols. are read through window 288, and if correct the ticket isthen printed.

'To accomplish the automatic succession of one escapement unit after the other, a series of twelve contact make and break magnets are provided, as 328. Also a set of twelve units of ratchet magnets, Mil-33!) and a thirteenth unit of the same.

Magnet 328, a plan of which is seen in Fig. 14, a side elevation in Fig. 6 and an end elevation in Fig. 18, is comprised of base plate 33f affixed to floor 3372 of the machine. Riser 33:3 supports magnet 334, and pillar 335 serves as a pivot for a double pendant arm, 33iiii3'i working as a unit. One arm makes contacts are, see, 3M and the other the two contacts M2, 343 when the armature is drawn in, breaking the contacts 340, 34!. When the magnet is energized the catch 3% looks the armature in that position, until it is cleared later by a manual operation. This is accomplished by means of crank 5 45, affixed to shaft 346 journalled in side 36? of the main frame and standard 348 at the other end mounted on base 332. Fixed on shaft are cams 349, one for each catch 344.

The de-energization of magnet.

When the crank is rotated these cams depress catches 344, which are pivoted in lugs 350. This frees the bottom end of 336 and it is drawn back to its initial position by spring 352, breaking contacts 342, 343 and remaking contacts 339, 340, 34L This re-setting or clearing takes place after the function is complete in order to clear the machine for a new operation.

Operated in conjunction with units 328 are units 329-330, the electrical connections of which will be described later. When magnet 353 of unit 329 is energized it attracts armature lever 354, mounted on lugs 355 set in side wall 313, and restrained by spring 356, which is overcome by the magnets action. When the arma ture is attracted an electrical contact is made from the armature through leaf contact 351. This energizes magnet 358 of unit 330, which has as an armature a bell crank lever 359, pivoted at 369. Pegs 36:, 362 limit the movement of armatures 354, 353.

When contact 351 is made, magnet 353 attracts the armature, overcoming spring 363. This throws catch 364 against the end of armature 354, which remains locked up, even after 353 is de-energized, until the circuit of magnet 358 is broken at another point, which unlocks armature 354 and breaks contact 351.

A contact block 364 on armature 354, but electrically isolated from its serves to close an electric circuit through leaf springs 365, 366 when the magnet of armature 354 is de-energized. The contact is ordinarily made as armature 354 normally rests against peg 36!.

There are thirteen of these units 329330 in the apparatus, twelve in connection with the automatic transferring of alternating current from one escapement unit to the next, and one used in connection with escapement arm clearance.

The apparatus is started by turning on the motor by motor switch 292, the units 328 having first been cleared by the manual operation of crank 345. When the motor is started the friction drums 46| tend to rotate the script wheels and typewheels.

The high tooth, 326, however, prevents. The sending operator is in telephonic communication with the printer operator and when the sending operator announces that his machine is set and ready to transmit, the printer operator closes line switch lever 361 against spring 360, lever 361 being pivoted in side wall 369. In the normal or open position of the switch lever it connects line to earth. When the switch 361 is closed, this contact is momentarily broken; the line is connected to the apparatus and earth is reached after passing through the apparatus.

When lever 36'! is in the dotted line position 310 seen in Fig. 14, it connects line to apparatus. When closed, lever 361 is locked by bell crank lever catch 31! in opposition to spring 3'62, and cannot be manually released. When magnet 313 is energized by a local circuit, which happens only after the whole apparatus is set for printing, the lever 361 is released. When necessary in case of an emergency lever 301 may be tilted out of the plane of the paper and may thus be freed from 3?]. If this occurs during operation it leaves some of the magnets locked up. They may be cleared as described later.

The thirteenth set 329, 336 does not employ the contacts 364, 365, 366. The thirteen sets are arranged on the wall 313, but if desired may be placed under the gears 244. Platform 314 is attached to wall 369 and carries contacts 315, cutting the machine out of line, contacts 316 cutting it in line, and magnet 313, pivot 31? and bell crank 3'.

An emergency switch 3T8 closes contact 319 to clear the escapement arms 3H, as described later.

When all the typewheels have been set the printing function is carried out. A printing arm 386 is seen in side elevation in Fig. 6, section in Fig. 17, partly in front elevation in Fig. 18 and indicated in plan by dotted lines in Fig. 14, being above the plane of the paper. This arm is afiixed to two plunger rods 33!, 382. The printing arm is of H shape, one staff of the H, 393, extending over the type, and the cross bar of the H reaching to the portion connected with the plunger rods. Bar 383 is hinged at 334 so that it can swing up on arc indicated by dotted line 385, Fig. 17. A thumb plate 336, rotating on an axis pin 381 when turned parallel to bar 383 permits the latter to be raised. The ticket may then be inserted in grooves in the bar 363 to be printed. When the thumb plate is turned parallel to the cross bar of the H it holds the bar 383 solidly in the printing position.

Two grooves are shown in bar 383. One is for the ticket and the other for a duplicate which may be printed by the insertion of a piece of carbon paper between the two.

A masking plate, stencil or matrix 388, Fig. 20, is fitted over the ticket, the type appearing in the apertures as 389. The underside of bar 383 may also be routed out in the portions corresponding to those of the masking plate between the apertures and the edges as 390. Thus no pressure is applied to any but the printing surfaces, and the rest of the ticket is not smudged.

When the printing lever is pressed down the printing is effected by an inked ribbon 341i, similar to a typewriter ribbon, which drawn across the type slightly between printings. The ribbon is in the form of an endless belt. Its upper stretch across the type is carried by rollers 392393. It passes down from 393 to roller 394, being drawn down by pressure rollers 395396, mounted on standards 391, 398, 393 set in the base. Roller 396 is fitted with gear 400, which is engaged by gear 40f on shaft 462. Gear 40! is stripped of teeth for half its periphery, so that the ribbon does not move during the printing stroke but moves at its conclusion, through the latter half of the rotation of shaft 402. From rollers 395-396 the ribbon proceeds under roller 394, then along the base through passage holes in the partitions and standards again to roller 395 and then up to the starting point 392.

The printing impression is effected by rotating crank 403, afiixed to shaft 402 for one revolution. Shaft 402 is journalled in wall 369 and standard 399. One side of clutch 404 is afiixed to shaft 402. In line with shaft 402 is shaft 405, journalled in standard 406 and wall 401. The end of 405 next to 402 carries the driven member of clutch 404. Clutch 404 normally stands engaged, through clutch lever 408, pivoted in standards 409, 4"] in the base, being drawn closed by spring 4| I extending from pedestal 4| 2 on journal standard 406 to lever 408.

Shaft 405 has afiixed to it mitre gear 4 I3 which engages mitre gear 4| 4 on shaft 4E5, journalled in standards M6, M1, M8 in the base. Shafts 405 and M rotate in the ratio of one to one, shaft 405 being the driving member. Shaft 4I5 carries aflixed to it cams 4I9420. Plunger rods 38!, 332 carry arms 429, 430. When cams H9, 423 are rotated by crank 403 through shafts 432, 405 and M5, they press on arms 429, 433 and draw down bar 333 and make the printing impression. This occurs at the end of the first half revolution of crank 333. The latter half revolution allows the plunger arms to rise and causes the progress of the ribbon to take place. Thumb plate 333 is then turned, 383 lift-ed and the ticket removed.

In order to prevent backward rotation, shaft 432 is fitted with a ratchet wheel 33l and pawl 432 and shaft 335 is fitted with ratchet wheel 333.

In order to prevent crank 3113 from rotating more than once at a time, cam 335 is fixed to it, inside of wall 333. In Fig. 18 the cam crank 403 is indicated in dotted lines, and a chain dotted circle indicates its radius of action. The surface of cam 435 retreats to shoulder 333. Magnet 431 has armature lever stop peg 438 and armature lever 333, retracted by spring Mil. The stop end Ml of lever 333 fits under the shoulder 433 and rests on the top of pillar M2, and has shoulder stop 333. In the View of Fig. 14 end MI is preventing the further rotation of crank 403, having followed the cam surface in under the shoulder in the previous rotation, drawn in by spring 333. Crank 333 cannot be turned backward at any time on account of pawl 332 of ratchet 331. It thus remains locked up until all of the typewheels are set, when magnet 331 is caused to function, drawing stop 33i from under shoulder 433. Catch 43 1 is mounted on pivot M and has arm M3 which is drawn upward by spring M1, limited by stop arm M8 and peg M9. When end Mi of lever 439 approaches wall 313, its stop 333 clears catch 334 which then rises so that 443 cannot return when the magnet 333 is de-energized. Once drawn towards wall 313 end Mil clears shoulder 43!) and cannot impede it again until peg 653 on the periphery of cam 435 is caused to strike beam 346 of catch M4 and depress it. This depression forces catch 444 down below stop catch 34-3 of end MI, and it retracts, drawn by spring 433, as magnet 431 has in the meanwhile been de-energized.

This does not occur until crank 4133 is partly rotated, that being made possible by its being unlocked by the withdrawal of end Ml. As the cam is rotated end Ml follows it and again is under shoulder 336 at the end of the rotation. This arrangement prevents crank 433 from being rotated prematurely, it being automatically looked after one revolution until time for another printing to take place.

Shaft 132 carries three commutators, 15i, 452, 453, with brushes for closing contacts 354, 355, 453, at certain angles on the rotation of crank 433, as later described.

The top cover is in contours, going under type printing bar 383 at 451, over the escapement wheels of shaft 233 at 458 and rising in housings at 333, 333. At 364 the top contains the window 238 for viewing the script wheels.

Fig. 21 is a section of friction drum Mil, which enables shaft 233 to drive the gears 289.

Fig. 22. is a plan of the spring leaf portion of 432. Drum 33! is affixed to gear 239. Spring disc 462 is affixed to shaft 243 by tongue and groove engagement, the tongues on 333. Spring disc 332 thusrotates with shaft 238 at all times. It has four wings as 463 turned down. The bottoms of the wings rest on gear 239 and the top of the wing disc table on the inside of the drum MN. The pressure of the spring wings is sufiicient to carry gear 239 along unless it is stopped; when the Wings rub over the surface of gear 239, ready to start it again when the obstruction is removed. One motor thus supplies friction drive for the seventeen gears 283.

Figure 24 is a diagram of electrical connections for the printer.

At I39 the printer current is superimposed on the telephone wire [38-443 at the sending end. At the receiving end of the line at Ml the printer current is deposed from the telephone line by apparatus 132 well known in the art.

Telephone line 533 leads to ear phones 5! and earth 532.

Line 533 goes to magnet 334 and from there to the contact 316, made by manual operation of starting lever 331. When lever 331 makes contact at 311, the apparatus is out out, the line being earthed through lead 534 and earth contact 505.

Four units as shown, E, F, G and H, corresponding to units A, B, C and D of the sender. Any number of units may be used, preferably inserted between units F and G. In the drawings unit E is shown as having operated, unit F about to be operated and units G and H awaiting operation.

Arm 506 of bell crank lever 336 carries two contact plates on the under side and a connection to ground. On the upper side of 331, a twin of 336, is a contact plate which makes two contacts. On the underside are contact springs 339, 343 and 3M, and on the upper side contact springs 342, 333.

When arm 5% is in the position shown in unit F, circuit El exists, made up of line 533, magnet 333E, contact 313, brushes 333-3 lll through contact block 331 on under side of 596, lead 5381,, to magnet 3MB, return lead to magnet 353E, lead 333 to contact spring 33!, block 503 and lead M3 back to ground 5ll l5il5. If the line circuit is not strong enough, relays may be inserted at points 3H or 512 or in lead 533.

When the alternating impulses arrive they do not aifect magnets 334E and 353E, but do operate the polarized magnet 3l3E, pulling armature arm 311 back and forth and permitting 3M and 3E5 to escape tooth by tooth until the selected 7 position is reached. When the prolonged impulse occurs, on either phase, magnets 333E and 333E are energized and function. Magnet 353E responds first. It completes circuit E2 as follows: Line 533, magnet 334E, contact 313, lead 5H3, arm 35 5, contact 351, lead 5M, magnet 358E, lead M5, lead 5m and to earth 533505. When armature 353 of magnet 353E is locked up by bell crank armature catch 333 of magnet 358E, contact 331 is made and continues closed while circuit E3 exists, energizing magnet 358E, which retains 333 locked up after 333E is de-energized, and until 333E is de-energized.

When armature 354 is locked up, contact block 363 attached to armature 354 but electrically isolated therefrom, breaks contacts 335, 366.

Slightly subsequent to the action of magnet 333E, magnet 333E, energized at the same time, attracts armature 333 which is locked up by catch 3 33. This causes arm 333 to rise breaking contacts 333, 333, Ml, which breaks circuit El. This leaves arm 3M of magnet 3illE in the last position to which it was drawn, and not subject to further change, holding its typewheel ready in the selected printing position.

The circuit of El which energized magnet 334E is broken but magnet 334E remains energized through the new parallel circuit through it of E2. The breaking of contact at 36 prevents lead |6 from passing the prolonged impulse of the line cLurent to 3345, which would otherwise take place through contacts 335, 365, 3% and line 5H.

Coincidentally with the action of magnet and magnet 353E, local magnet A25 of the sender functions, breaking local circuit Adi, and de-energizing clutch magnet A9. Ali now breaks the line at contact 525. The apparatus is so adjust ed that magnet 353E locks up armature 35d, magnet 334E locks up and magnet AaEEB locks up Aa22 in close succession in the order named. These magnets thus have time to function before the line is broken at 525. When the line is thus broken magnet 558E is ole-energized. This unlocks 354 and makes contact between 364, 365, 366. Magnet 335E is also de-energized but no function results since is locked up by 344. The contact at 359, 365, 995 is made before the second disc unit of the sender begins sending alternating impulses. When makes contact at I29 and sets up the main line more time is taken than by the descent of Line B2 is made up as follows: lead from sender, line, lead 503, lead 5H5, contact 352, block 5%, contact 343, contact 365, block contact 3% and lead 5H. This circuit remains intact during the following operations, eXcept that the line by-passes magnet 334E, through 538.

Circuit Fl, through magnet 5343, is similar to circuit El, and the whole unit functions as did El, which is shown as having completed its functions, 334E being locked up and block making line 5|].

Unit G functions in a similar manner to units E and F. Unit H, however, being the terminal unit functions slightly differently, in its concluding action.

Magnet 334E is energized through lead and locks up armature as before. When block 364 is dropped to contact 355, 35%, lead energizes magnet 43?. This attracts armature 439, and draws stop M! from under shoulder MI is then locked up by catch idd.

Printing crank 433 may now be manually retracted. As this occurs, stud 350 of earn 435 contacts with arm 4 15 of catch id-Li, and frees 44!, permitting it to be drawn back against cam 435, which it follows until shoulder is reached at the end of the revolution.

Meanwhile the commutators on shaft have come into action. commutator i5l has segment 523, with brushes 554. Shortly after the beginning of the printing rotation of shaft closes local circuit 5M5- with battery and magnet 3'53, which, on being thus energized frees lever 361. Spring 368 draws lever which makes contact 3H. This cuts out the printing apparatus and closes the line to earth for any uses of the sending apparatus.

The rotation of crank causes the printing to take place on the completion of one-half a revolution. Shortly thereafter commutator segment 526 of commutator strikes brushes This completes a local circuit 52?, having battery 528 and leads in parallel to the polarized magnets 2). This is a direct current and draws all the arms back to the left which are on the right and holds all the arms on the left which were on the left. This positions the arms for the. initial position on the next functioning of the machine. As the crank 353 continues to advance circuit 52'! goes dead, the commutator segment passing to the brushes.

Next commutator segment 529 strikes brushes 456 and completes local circuit 530, with battery 553i and magnet 353K. This attracts armature and closes contact at 357K, and completes circuit 532 with battery 533, through contact tit iX, magnet and battery 533, and in parallel with the tilting magnets 309, and their circuit breakers. This includes contact 321 between sp ings and 323 in series with its tilting magnet winding 399. When direct current circuit 532 closed all the tilting magnets are parallel and are energized. This causes all arms 3i i to be tilted free of the escapement teeth. The escapement shafts are in various angular attitudes. When the escapement wheel teeth are cleared all the shafts begin to rotate. As each draws near to high tooth 326, cam 324 breaks circuit 532 as regards its particular magnet. The arm 3H descends and stops the high tooth 326. When all the cams 525 have broken all the contacts circuit is broken. It remains alive until the last of the contacts 321 is broken. Then it goes dead, catch 369 is released and contact is broken, since magnet 353X was de-energized by the passing of segment 529 as crank completes its rotation.

The clearing crank 355 is now rotated, which unlocks magnets to H and the motor is turned elf. When another ticket is to be printed the motor is turned on and switch 361 is turned to make contact 3'56.

The motor for the escapement shafts is shown at with circuit 534, switch lever 535, switch 535 and power leads 531.

An emergency lever 538 With switch 539 and leads 541i? is parallel with brush 456 and circuit is provided for operating the tilting magnets 359 in case of emergency, as when a mistake might be discovered during setting. This would be corrected by breaking line 503504 by switch 381 and then clearing the tilting magnets by switch 539, and rotating the clearing handle If it is desired to clear after setting and without printing, the clutch lever 498 may be drawn back and held manually while crank 403 is rotated. This is followed by turning clearing crank 3 35, when the machine will be in readiness for another setting.

It is to be noted in the diagrams that batteries are provided for each independent circuit. This may be obviated by sources of current in multiple if desired. Grounds are also shown for the sake of clearness, but in operation it is likely that complete metallic circuits would often be employed, all of which is within the scope and spirit of my invention.

The apparatus may be arranged for use with a separate circuit from each sending unit to each typewheel unit, with an added circuit for the final impulse. This may be accomplished with high frequency multiple channel wired wireless r'ethods well known in the art.

25 is a diagram of the sending apparatus when each unit has a separate channel. Device iiiiil supe' i poses upon telephone line 60l with ground and ear pieces 503, the multiple high frequency channels needed.

Transmitting units J, K, L and M are provided, although a greater number may be used. To start the apparatus switch 62 is closed. This starts motor ed from power leads l2l. Motor 35 drives shaft l, fitted with spur gears 6 and clutches 8. After motor 35 starts shaft 1 it will rotate idly until magnets as J 9, K9, L9 and M9 are caused to function. When they are energized and cause clutches to engage spur gears, discs J l, Kl, Li and MI cannot start, being held by mechanical stop E la.

In order to energize the local clutch magnets, circuit 604 is formed. When ticket inserted in the machine makes contact li3l l4 .and switch 63 is closed, circuit EM goes through parallel leads to the clutch magnets, they being in parallel with its battery 6%.

In the illustration, Fig. 25, the clutch magnet armatures KM] and Mlii are shown closed, being in operation, while J N) and Llil are open, having already functioned.

The closing of armatures It) creates the line circuits and closes the clutches. The commutator discs will now function when stop 6% is removed.

Owing to the settings of the keys and to the fact that all the discs start simultaneously, some will be stopped before others are stopped. When the prolonged impulses occur, magnets as 2!] are caused to be energized, breaking their armature contacts. This de-energizes the clutch magnets and the clutches are disengaged, the discs returning to their initial positions independently of each other.

As in this form of connections the last disc is not the one which can be depended on to send the last prolongation, means is provided to send a prolonged impulse upon the completion by the last disc of its prolonged impulse.

For thispurpose magnet 60b is inserted in circuit 604. When all the contacts Jl25, Kl28, M31 and Ml3t are broken, the whole circuit 804 goes dead, and magnet 608 is de-energized.

Magnet 6% has armature tillB, on circuit Bill which includes contact Elli), battery Ell], contact at lever switch 63, and magnet fil l. When magnet fiilil is energized, armature see is attracted and contact 609 cannot be made. But when magnet 6% is de-energized by the braking of the clutch magnet circuits the circuit till is set up.

Magnet 6 has armature 6H2 with ground M3. When 6| l is energized it makes contact iii-l, which sets up the final line circuit M5, battery Hi6, magnet BI! and line lead BIB, to device iillll, arising at ground M3 and going to the printer. Contact Gi l is. locked up as long as magnet fill remains energized, but when the circuit goes dead from the printer, GM is not broken because 6H remains energized by circuit Hill. It is now de-energized through switch 63 breaking circuit $01, which allows armature M2 to retract and break 6l l. Switch 63 is so arranged that circuit 5% is closed before 607 is closed, so that armature 803 being attracted, circuit 69H cannot be set up at the outset. Or upon the mechanical restoration of contacts, as J i213, through the clear ing crank 32, magnet tilt is energized and circuit 6&1 prevented from being set up.

Thus the de-energization of magnet 6% through the breaking of all the local clutch contacts, sends a final direct current impulse to line which effects the function at the printer which was in the previous arrangement effected by the prolongation of the final disc impulse.

When switch 63 closes circuit 6M and engages all the clutches, and mechanical stops M and Ma are removed, the discs begin to send impulses to line. Disc J l starts circuit J 2, by connection with batteries J l25, J I26 and through brush 48 to lead J and thence to contact I24, magnet J1i20 and to line at device 600.

The alternating impulses pass to line and the prolonged impulse energizes magnet J7'20, which attracts armature J7'22 and breaks contact Jl23 which de-energizes magnet J9. This causes contact I24 to be broken, and the clutch to be disengaged allowing disc Jl to return to its initial position.

Meanwhile all the other units have been functioning similarly, and when the last is finished, Glfl circuit is completed. After the printer breaks circuit SIB, switches 62 and B3 are turned oh and the magnets and keys are cleared by the clearing cranks, ready for the next functioning.

When the high frequency multi-channel line reaches the printer, the channels are separated and deposed from the telephone line at by device ml, by means Well known in the art.

Phone line Hi2 leads to ear phone 103 and ground 164. Four channel leads, equal in number to the channels from the transmitting disc of the sender are provided, leading to magnets 33 lN, 3MP, 33462 and 334R.

Circuit Ni is made up of lead Na, magnet 334N, contact made by switch arm 367K designated HEN, lead 105 to magnet 3ION, operating arm 3i lN to set the escapement wheels, back through lead lllfi to spring contact 3MN, through arm 506 of bell crank armature 336N to lead Ill! and to common ground return lead 101, lead 198 and ground M19. The alternating impulses received on this circuit operate magnet 3IHN, and when the prolonged impuse comes in it actuates magnet ?MN, attracting 336N which is locked up by catch 33m. Current through Na, however, closes contact through spring 342N, block 509 and 343N. Arm MEN being locked up these contacts are held in force after current through Na is broken by the sender.

Contacts 3521i, 569 and 343N are in circuit N2, which derives current from the final circuit 618 of the sender. N2 starts at 10!, follows lead III to MEN. All the units operate similarly and start simultaneously. When all have functioned all the contacts as HEP-3431?, 34262-3436), and 342R- 3MB are closed in series to provide a path for current from M8, the final impulse which goes through lead H2 to magnet 43TZ and back through lead ll-3 to common ground IN-108- 109.

The functioning of magnet 43'lZ is similar to the function of magnet 43'! previously described and the action of the printing crank and other parts is similar, and they are numbered similarly.

When two tickets are desired to be printed which are for adjoining seats and diiTer only by the seat numbers, or when tickets for seats in adjoining rows in a block are desired to be printed, I provide means for holding the main portion of the ticket printer wheels set, while only the smaller portion including the numbers is changed. This saves the operators considerable time, as only a few wheels at the ends need to be re-set.

In the diagrams in which these portions are shown Figs. 23, 24, 25, 26, only four units are indicated, the retained set portion consisting of two units and the changeable portion of two units, but any number of units may be included and the division made between them at any desired point.

Figs. 23 and 24 indicate the means used in connection with the single channel line, and Figs. 25, 26 the means used with the multiple channel line.

In Fig. 23 a switch, I43, is inserted in circuit Anal, in series. When this switch is closed, the circuit functions normally for the whole range of units. When the switch is opened circuit AM is dead. The switch goes over and creates circuit I44. Circuit I44 comprises contact I45 of switch I43, lead to switch 63, switch contact at switch 63, contacts I33 II4, battery I22 and leads to circuit CcI, circuit I44 being in parallel with the leads to contact BIB.

After transmitting an entire range of discs and after the printer is set to hold part of them and to re-set some, as 3IOG and 3I9H, the sender operator clears his machine with the manual clearing levers and sets keys for discs CI and DI. The motor has been left running. I-Ie closes contact I45 with switch I43 and closes switch 63. Magnet A9 is thus Icy-passed and does not function, hence no signals can be sent by disc AI. As contact AIS is not closed, depending on AI 6 functioning, magnet B9 gets no current and disc BI cannot function. Circuit I44Ccl energizes magnet C9. The operator then frees disc C and D of stop 64a. Disc CI then sends current to line until the prolonged signal energizes magnet C025 and breaks the clutch magnet circuit, which in turn sets up the next circuit for disc DI. Any number of units may be by-passed at the outset and any desired number retained for the re-setting of the final typewheels of the printer.

In order to cause the printer to function in a corresponding manner, a by-pass unit is inserted between magnets 3345 and 334G, in the line at point 5I9. This by-pass unit could be inserted elsewhere, as desired, to agree with a different setting of switch I43 of the sender.

The by-pass consists of the switch lever 36'IZ, magnets 3'I3Z, switches and connections. The by-pass unit is switched in after the printer is set for a complete printing, but before the printing crank is turned. The following functions are brought into play to hold the typewheels desired to be held and to permit the clearing of the few to be re-set.

The operator cuts off the left hand units through breaking circuit 52'! at switch 540. He also cuts off the left hand part of circuit 532 with switch 54!. He also breaks line 5I9 with switches at three points, 542, 543, 544. The breaking of circuits 527 and 532 prevents any impulses from reaching the left hand units from the printing crank commutators, and so they remain set, without being cleared.

The operator now prints the ticket. In the function the units (HUG and 3 IGH clear. Switch starting lever returns to contact 311, magnet 313 being energized by circuit 524. Armature 3' has an extra notch 546. Both notches are escaped by 36'! when magnet 313 is energized.

In order to receive new impulses to set only units 3IOG and SIQH, the operator turns the clearing crank 345, then throws lever 361' over to the point where it is caught by the second notch 546 of armature 3'! I. This positions it in a median location, not making either contacts 376 or 311. No current can now pass to magnets 334E or 3341 and at the same time the line is not grounded. The operator then closes switch 545, setting up circuit EIZ, through lead 54'! to 503Z and magnet 334G, which then functions in the same manner that magnet 334E functioned before.

When circuit EIZ is broken by the energizing of magnet 334G by the prolonged impulse, circuit EZZ is set up similar to circuit E2, through magnet 334G, lead 5I3Z to armature 354G, thus supplying the second circuit to keep magnet 334G energized. When contact 351G is broken by the sender, magnet 334G is by-passed by lead 5I6Z, similar to lead 5H5, to spring contact 520, and so on to lead 52I to magnet 334H, which then functions as when the whole range is operated. Units 3IOG and 3IOH are now set. The second ticket is now set up. If the operator desires no more tickets adjoining he cuts circuit EIZ by turning off switch 545, and remakes contacts at 540, MI, 543 and 544. He then turns the printing crank and the whole range of typewheels is cleared.

Magnet 3132 is in parallel with magnet 313, and when 3612 is freed and breaks contact 3'I6Z, lever 36'! is freed of the second notch 546 and 36'! is returned to the initial position, while 36IZ has cut out the by-pass unit, which can only be cut in again by the manual operation of 3612.

Switch 548 is arranged to make and break contacts 540, 54!, 542, 543 and 544 simultaneously.

In order to effect the same functioning in the high frequency channel wired apparatus, additions are made as indicated in Figs. 25 and 26.

In the sender Fig. 25, switch 62I is separately in series with 6| 9 and 620, they being isolated from each other. As shown closed the switch permits normal operation of the whole range of sending discs. When it is opened it breaks contacts by magnets J9 and K9, which cannot then be energized by circuit 604. Units J I and KI are thus left idle and units LI and MI are free to function as before.

After setting the first ticket and before setting for the coupon of the second ticket, the clearing cranks 32 and I62 are turned. Keys for discs LI and MI are then set and the apparatus started as before.

In Fig. 26 the printer is provided with a supplementary switch arm 36'IY, similar to 361K, except that it makes contacts for each of the magnet circuits to be operated thereafter while 36'IX supplies current for all. The switch arm 36'IZ will serve the purpose when fitted with eXtra contacts.

When the entire printer is set for the first ticket the operator does not at once print. He first breaks contact H4, cutting off circuit 52'! from the units to the left, and he also cuts off the units to the left from circuit 532 by breaking contact II 5. These circuits may be broken by switch 548 when it is not connected with 542, 543 and 544.

The printing of the first ticket now takes place. It frees units Q and R but cannot affect units N and P which remain set. In order to re-set 3IOQ and 3 IGR for the coupon of the second ticket, the clearing crank 345 is rotated; lever arm 361K is closed to the second notch 546 and lever arm 36'IY is set to the position shown in Fig. 26. The setting of lever arm 361K to point 546 insulates the circuits of units 334N and 334P from the line but does not ground the line as is the case when it is on contact 317.

The printer operator is now ready for current from the sender, and so notifies the sender operator by telephone.

Circuit Qa from line goes to magnet 334Q, then to contact 3'I6Y at lever arm 36'IY, thence through 'ZUEY and 'IO5Q2 to magnet 3IUQ which sets the typewheel, back through spring contact 34IQ, to lead 'III) and thence to common return 'IH'I. When the prolonged impulse comes magnet 334Q, is locked up and the circuit goes dead at the sender so that 3IOQ is not moved again.

Magnet 334R is operated similarly. When they
